Darril's book makes a huge point to make it clear that a protocol ID is not a port number. But it hasn't gone into detail about what it is or how it is different. Does anyone know the answer to this?
Decide what to be and go be it.

    It's very doubtful you'll have to know anything about protocol ID for the test. It's just a number to represent what the protocol is. These are necessary since there are so many protocols out there. Knowing the common port numbers you are only exposed to a small number of protocols but the number of them is huge, a lot of proprietary protocols.
    It basically specifies the protocol type as shown here TCP / IP Suite |ATMP | L2F | L2TP | PPTP | DHCP | DVMRP | ICMP | ICMPv6 | Protocol |
    No longer work in IT. Play around with stuff sometimes still and fix stuff for friends and relatives.
